DTC P0096: Intake Air Temperature Sensor 2 Circuit Range/Performance Bank 1: Notes

-
DTC detecting condition:

Detected when two consecutive driving cycles with fault occur.

Trouble symptom:
- Improper idling
- Poor driving performance

NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DOTC)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

CHECK DTC .
1. Turn the ignition switch to ON.
2. Using the Subaru Select Monitor or a general scan tool, read the DTC of [Engine]. Ref. to COMMON (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
Is DTC other than P0096 displayed? (Current code)

Yes: Check the appropriate DTC using the "Diagnostic Trouble Code (DTC)". Ref. to ENGINE (DIAGNOSTICS) (H4DOTC)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

No: Go to 2.
CHECK DATA MONITOR .
1. Remove the manifold pressure and intake air temperature sensor from the intake manifold assembly with the connector connected. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>MANIFOLD ABSOLUTE PRESSURE AND INTAKE AIR TEMPERATURE SENSOR>REMOVAL
2. Turn the ignition switch to ON. (Engine OFF)
3. Use a fan to blow ambient air to the manifold absolute pressure and intake air temperature sensor.
  NOTE: This is to remove heat inside the engine compartment and read the ambient temperature.
4. Using the Subaru Select Monitor, read the value in [Intake Air Temperature (B1-S2)].
  NOTE: For detailed operation procedures, refer to "COMMON (DIAGNOSTICS)". Ref. to COMMON (DIAGNOSTICS)>DATA MONITOR .
5. Use a heater gun to blow warm air to the manifold absolute pressure and intake air temperature sensor to read the value of [Intake Air Temperature (B1-S2)] again.
  WARNING: Be careful not to burn yourself, deform parts, or cause their erosion.
Does the value of [Intake Air Temperature (B1-S2)] change after blowing warm air?

Yes: Go to 3

No: Replace the manifold absolute pressure and intake air temperature sensor. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>MANIFOLD ABSOLUTE PRESSURE AND INTAKE AIR TEMPERATURE SENSOR .
CHECK MANIFOLD ABSOLUTE PRESSURE AND INTAKE AIR TEMPERATURE SENSOR
Check the manifold absolute pressure and intake air temperature sensor. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>MANIFOLD ABSOLUTE PRESSURE AND INTAKE AIR TEMPERATURE SENSOR>INSPECTION

Is the check result OK?

Yes: Repair the poor contact of ECM connector.

No: Replace the manifold absolute pressure and intake air temperature sensor. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>MANIFOLD ABSOLUTE PRESSURE AND INTAKE AIR TEMPERATURE SENSOR
